How to make an exclusive gift of a usual white mug? Take a white porcelain mug, outliner and a brush. Squeeze the paint straight out of the tube and onto the porcelain. If you mess up, just wipe the paint away with a wet paper towel. Some porcelain paints are not recommended for surfaces that come in contact with food. So just to be safe, don’t paint the inside of your mug! Once you’ve finished your masterpiece let the paint dry for 24 hours. Then, bake your mug according to the paint package instructions. After baking turn off the oven and leave the mug inside until it has gradually cooled to room temperature. Your masterpiece is ready; it’s a great gift and a fine personalized mug.
